AUTOMATIC SUPPLY-VALVE.

Specification of Letters Patent.

Patented tlluly 2, 191%.

Application filed September 19, 1914.. Serial No. 862,615.

To all whom it may concern:

Be it known that I, EARL G. WATROUS, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Automatic Supply-Valves, of which the following is a specification.

My invention relates to a Valve device for automatically supplying water under pres sure to tanks, such as the service tanks for (lining cars and the like, to which water is supplied under pressure at the terminal points of the railroad and also at certain division points. The object of my invention is to provide a simple, efficient, and reliable automatic valve operating in connection with a water tank or receiver which is such to overcome the objections in the practical operation of the present construction of supply valves.

Heretofore, articularly in the case of the service tanks ibr dining ears and the like, the automatic valve has been located Within the tank itself, being operated by a float, but in practice it has been impossible to completely fill the tank with water, besides which the surging of the rather large body of water in the tank, when the car is traveling on the road, causes displacement and injury to the valve and its float and renders the same unreliable in use.

My invention overcomes the difliculties above mentioned by providinghan automatic supply valve located extraneous of the service tank and connected therewith and operating in such manner that the tank can be filled to full capacity. Moreover, the construction of valve device is such that it is not subject to any injury or derangement as is encountered in previous constructions of supply valves.

In the drawing Figure 1 is a sectional elevation of my valve device illustrating a portion of a tank in elevation; and Fig. 2 a section on the line 22 of Fig. 1.

Referring to the present embodiment of my invention as herein shown, the valve device comprises a case of suitable shape and din'lensions and here shown as consisting of a cylindrical body 1, and top and bottom heads 2 and 3 both of which have central openings. Through the opening in the top head there passes a "ertical supply pipe 4 onto which screws a coupling sleeve 5 having a central opening or conduit communicating with the supply pipe. This coupling sleeve is secured to a supply pipe or nozzle 6 by means of the coupling nut 7. The inlet pipe 4: extends centrally and downwardly into the valve casing and is secured at its lower end to a'valve seat body 8 whose lower end is screw threaded into the screw threaded opening in the bottom head 3 of the casing. This valve seat body has an inlet port 9 on which seats a float controlled valve 10.

According to the construction shown in the drawing, the valve 10 has a transverse opening l0 through which passes an irregular shaped lever 11 which is pivoted to the valve seat body at 12. The valve is thus mounted on and carried by the lever 11 at a point in termediate the length of the lever, with the result that as the lever is moved up or down the valve itself is correspondingly moved. The lever 11 is one of the levers of a compound lever system which includes a second lever 13 which is pivoted intermediate its length at 14 upon a bracket arm 15 projecting from the valve seat body. The short arm of this second lever is reversely turned with respect to the long arm and the free end thereof cooperates with the free end of the lever 11. The long arm of the lever 13 extends around the valve seat body and on the other side thereof its free end is pivotally connected by means of a link 16 to the float device.

The float employed herein is of the bell shaped type consisting of a bell 17 having a central depending tube 18 which is fitted to slide up and down upon the inlet supply pipe 4. The link 16 is pivotally connected at its upper end to the tube 18 with the result that the movement of the float is communieated through the compound levers to the valve 10 and the latter thereby opened or closed accordingly as the float is lowered or raised. When the float is in'its uppermost position, as shown in Fig. 1, the valve is held to its seat with a considerable pressure. When the level in the service tank. and correspondingly the level in the valve casing, is lowered. the float will descend and the valve will be opened for the admission of water whenever a supply of water is connected with the supply pipe 6. The water thus supplied is under pressure and the construction is such that when the tank has been completely filled, and in fact when pipe 23 has been. partially filled as shown in the drawing. the valve will automatically close by reason of the pressure exerted by the lilo water upon the float. which pressure is transmitted to the compound lever system to the valve. The valve will thereupon be seated against the pressure of the water supply and no more water can be supplied to the tank.

The valve device is located extraneous to the tank 19 and the bottom of such casing is connected therewith by means of the inlet pipe 20. Both the casing and the tank are connected to an air vent pipe 21, the former by means of the pipe 22 and the latter by means of thepipe 23. The valve device is so located with respect to the tank and the leverage of the levers acting upon the valve is such that the water level maintained by the valve device is above the top of the service tank, with the result that the tank can be completly filled with water, the air escaping through the pipe 23 during the filling operation.
